esaProbeScheduleGroupInterval is a read-create Unsigned32 giving the number of seconds between successive runs, and it is only meaningful when esaProbeScheduleGroupType is periodic. An administrator sets this to control how often a recurring diagnostic or SLA-verification cycle repeats for the whole group of probes. For example, setting this to 86400 seconds makes a periodic group of probes automatically re-run their test once every day without any manual intervention.
